Recently, an experiment designed by Prof. YAN Xingbin's group from the Lanzhou Institute of Chemical Physics (LICP) of the Chinese Academy of Sciences has revealed that applying an external magnetic field can induce capacitance change in aqueous acidic and alkaline electrolytes, but not in neutral electrolytes. The experiment also shows that the force field can explain the origin of the magnetic field effect.
